 The utility runs individual modules to generate malicious traffic. To perform all available tests, simply use `flightsim run` which will generate traffic using the first available non-loopback network interface. **Note:** when running many modules, flightsim will gather destination addresses from the AlphaSOC API, so requires egress Internet access.

+The utility also has a `get` command which can be used to query information that can later be used with the simulation modules. At present, a list of C2 families can be obtained to be used with the C2 module. To see how to use the `get` command, run `flightsim get -h` as below.
